Contents l.jpg
Contents in China

  • Climate change and its impacts in China

  • Policies for food production in China

  • Food production and climate change

  • Build adaptive capacity for food production

  • Case study in Chongqing China


Climate change in china observed l.jpg
Climate change in China- in Chinaobserved

  • IPCC third assessment report identify an average increase in global temperature of 0.4~0.8 ℃ in past century

  • Over the same period in China preliminary results show this temperature increase to be between 0.5~0.8 ℃, the impacts of climate change in China were different and severe.

Climate change has been found and will be not avoidable in China, What impacts have taken and will take to agricultural production by climate change?


Adverse impacts in china l.jpg
Adverse Impacts in China China, What impacts have taken and will take to agricultural production by climate change?

Cold damages after mild spring that lead to damage on earlier buds and flowers

Climate change can take impacts on agriculture, which involves adverse and benefit! Can we do some to get benefit more and adverse less?


Policies for food production in china l.jpg
Policies for food production in China involves adverse and benefit!

Target of 95% self-sufficiency is a central tenet of China policies for grain food production

  • Household responsibility system

  • Grain and cotton protected price

  • Long-term farm land rent contracts

  • Return low quality grain land to green


Conflicts food production and environment l.jpg
Conflicts involves adverse and benefit! -Food production and environment

  • Water and soil erosion

  • grassland degradation

  • Salinity land

  • Water pollution

  • Crop residues

  • ………………..

involves adverse and benefit! Peak of 1.6 billion population around the year of 2030;♠ Heavy pressure for more animal food and dairy needed;♠ China joins WTO and will suffer by international products;♠ etc ……..

Challenges of food production in China

eg. Climate changing


Slide15 l.jpg

Climate change will take extra challenges to food production in China, as well as agricultural development will also feed back to climate!Build capacity to balance agricultural SD and climate change!


Build adaptive capacity for food production l.jpg
Build adaptive capacity for food production in China, as well as agricultural development will also feed back to climate!

  • Public awareness

  • Technology improvement

Integratedfood production strategieswith climate change!!Case-study in Chongqing China

Chongqing in China, as well as agricultural development will also feed back to climate!– theyoungest municipal city in China


Objectives of the chongqing study l.jpg
Objectives of the Chongqing study in China, as well as agricultural development will also feed back to climate!

  • Develop strategies and policies that meet development priorities of Chongqing and address climate change

  • Enhance local people ability to develop effective adaptation strategies that will help to minimize the negative consequences and maximize the positive effects of changing climatic conditions on agriculture.

  • Draw lessons for applying such a strategy in other parts of China.


Relative information chongqing l.jpg
Relative information-chongqing in China, as well as agricultural development will also feed back to climate!

  • Chongqing is an agricultural production base of China.

  • People living in the countryside is about 24 millions which takes account about of 75% Chongqing total population.

  • The rural area accounts for more than 95% of Chongqing total territory.


Climate characteristic chongqing l.jpg
climate characteristic in China, as well as agricultural development will also feed back to climate!-chongqing

  • Warm winter with less sunshine and frost

  • Earlier spring with cold wave and hails

  • Hot summer with abundant sunshine and flood or drought

  • Cool autumn with less sunshine and cloudy rain

  • Drought, flood, higher temperature


Agricultural development strategies l.jpg
Agricultural development strategies in China, as well as agricultural development will also feed back to climate!

  • ten agricultural industrialization activities

  • One million MU high quality Chinese herbs industrialization project;

  • One million MU natural spicery industrialization project;

  • One million MU bamboo sprouts industrialization project;

  • One million MU Rapeseed industrialization project;

  • One million MU ornamental plants industrialization project;

  • One million ton citrus deep process industrialization project;

  • One million ton high quality grain deeper process industrialization project;

  • One million Dan high quality Silk worm (cocoon) industrialization project;

  • One million of grass-feeding livestock industrialization project (including diary, cattle, goat, rabbit, number)

  • One million exported high quality pig industrialization project


Agricultural development priority l.jpg
Agricultural development priority in China, as well as agricultural development will also feed back to climate!

  • High quality rice planting

  • Deep process industrialization

  • Animal raising


Work focus on l.jpg
Work focus on in China, as well as agricultural development will also feed back to climate!

  • What scientific, technological and societal responses are required to deal with the impacts of climate change on regional agriculture?

  • What climate-friendly and climate-safe technologies could be implemented in this region?

  • What role do the food industry and markets have in the development of a climate friendly and climate-safe agricultural sector.

  • How can recycling of waste and closing the nitrogen and carbon cycle between various sectors contribute to the sustainable development of the region?
